In a right-angled triangle, the lengths of two legs are 5 cm and 12 cm. What is the length of the hypotenuse?
Options:
A) 8 cm
B) 13 cm
C) 15 cm
D) 17 cm
Answer:
B) 13 cm
Solution:
Use the Pythagorean theorem: Hypotenuse² = Leg₁² + Leg₂². Therefore, Hypotenuse² = 5² cm + 12² cm = 169 cm². Taking the square root of both sides, Hypotenuse = √169 cm = 13 cm.
